Horde causing high server loads

[gflamerich]

Hi
Since a few days we are having some problems with horde at our box.
We found that Horde is satable consuming more than 90% of cpu for long periods of time.
When we notice high server loads, juts check at top and then kill the process (here is the line from this mourning, yesterday one was about the same)

PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND
20387 cpanel 16 0 8228 732 716 R 94.2 0.0 1072m 1 /usr/local/cpanel/3rdparty/bin/php /usr/local/cpanel/base/horde/imp/mailbox


This is the info of our version running
WHM 10.8.0 cPanel 10.8.1-S114
RedHat 9 i686 - WHM X v3.1.0


Thanks

We have this same problem with users who have literally thousands of messages in their inbox so when they first login or refresh the page, they consume large amounts of CPU.

The best way is to speak with the client and tell them to either reduce their inbox size or use different mail program

Thanks Hicom
But we received another solution that seems works perfect. Here is what to do

Yes this is common.

I recommend several things, is by clearing the horde database completely:

mysqladmin drop horde

mysqladmin create horde
/scripts/fullhordereset

And running a cpanel php upgrade:

/scripts/makecpphp

And /scripts/upcp --force

We applied that solution a few days ago, since horde is working perfect

Thx 4 sharing! It seems both cPanel and Horde are working better now

- Just to add an update:

1) Dropping Horde DB will delete any contact addreses the users have. so make sure to let them know

2) This doesn't seem to have completely fixed the problem. It is still using a high amount of CPU resources on one user account (he has 500MB worth of emails!)
